Used in steel, casting, petrochemical, breathable bricks, ladle lining, castables, prefabricated parts, ceramics and other fields, is an excellent refractory raw material. High refractory, high hardness, good thermal shock stability, good erosion resistance and wear resistance, stable performance.
Main uses: refractory materials, charge, castables, ramming materials, plastics, spray feeding, pressing, projectiles, coatings, spray coatings, fire mud, dry vibrating materials, artesian castables, coatings, refractory muds, etc. Such as: unshaped refractories, stereotyped refractories, corundum bricks, ladle refractories, neutral refractories, blast furnace hot blast furnace series combination bricks, high aluminum bricks, carbon-containing refractories, mullite bricks, cannon mud, spray guns, bulk materials, ceramic cups, clay bricks, combination bricks, corundum products, etc.
–Abrasives
Main models: 36# 46# 54# 60# 80# 100# 120# 150# 180# 220# 240# 280# 320 #wait
Abrasive belts, emery cloths, sandpaper, etc. coated with abrasives and resin grinding wheels and other consolidated abrasives, grinding sharp, heating rate is very low, grinding ratio is high, and less adhesion when used; The sintered abrasive made has the characteristics of no network cracks and no rust spots after firing.
F sand is used for resin, ceramic grinding wheel; P sand is used for the production of coated abrasives, such as emery cloth sandpaper.
